Digital City 79: Metrocard/MTA secrets; plus, we test the new 13-inch MacBook Pro

This week, we take a look at high-tech goings-on at the MTA (the agency that runs NYC's subways and buses), including an explanation about how those Metrocard readers work (or don't work. as the case may be) and why the agency is suddenly opening its data feeds to app makers.

We've also got a couple of new laptops to dish about, including the latest versions of Intel's Netbook-like Classmate PC and the eagerly awaited 13-inch MacBook Pro.

Finally, the U.S. Supreme Court is set to weigh in on a controversial California law restricting the sale of violent video games -- we cut through the clutter to talk about the actual legal issues at stake.

This week's giveaway? A cool prize package of ultra-rare video game goodies, including a Final Fight t-shirt and a Plants vs. Zombies iPhone skin. Watch the show for info on how to enter the contest (or just pop by our Facebook page).
